I'm here with a question and willing to hear(actually see)the answer.
Generally i have difficulties understanding evolution of behaviors. please help me to understand it.
For example how learned behaviors inherits through generations and became an instinct behavior?
For example every toxic snake knows how to use its poison.
Every child cries or Spiders know how to produce web...Birds
know instinctively how to build nests etc.
Thanks very much.
